Grandson comes in with 23,000.00. He deposits 17,700.00 to grandpa's business account. He then deposits 5200.00 to his parents account. Then deposits 100.00 to his own account. (all family works for business)

Question is: Should CTR should be filed for only the 17,700 on grandpas account, or on aggregate total of 23,000.(since this is the amount of cash that came across counter) listing all accounts affected?

Thanks...

You have $23k cash in, benefiting business and every owner of parents' account and his account.

The CTR should include all 23,000. You will have multiple accounts listed and multiple section A's for Part I, listing the grandson, grandpa's business, mother, and father all as benefiting from the transactions. I would list the grandson on the first page in section A and check "conducted on own behalf" for section B. Then I would complete the additional page of the CTR for the rest of the parties.
